Notes
Be sure to whip the royal icing long enough, about 10 minutes! It should be the consistency of soft whipped cream.
Wrap the piping tip of the royal icing with plastic wrap when not using and store in the refrigerator. You want to prevent the royal icing from drying and clogging the piping tip.
Store these cookies at room temperature in an airtight container for up to 5 days.
